well if you don't feel like levelin up I have a easy tactic to kill Irenicus well actually it ain't easy takes several relaods

Summon monsters doesn't matter what level near the entrance cast haste on your party too and have a lotta dispels ready when you see Ireincus blah blah blah run away down south and let ur monsters get slaughtered. After a while Irenicus comes and immideatly turn into a bloody slaya and attack and with ur tanks casts breach and other spell removing spells to inflict damage and make sure he doesn't have a chance to cast his spells and if it seems like you are going to die of being slayer too long change back hopefully you will win!!!!
